'10 Claims.

"My invention relates to an improvement in paint roller, wherein it "is desired to provide -a roller of the fountain type for use in applying paint or similar material to a flat surface.

In recent years, various types of paint have become popular, which may be eifectively applied by means of a -roller having a soft surface. In most instances this roller was dipped in an open container of paint and merely rolled upon the wall, the roller spreading the paint into a film evenly :over the wall surface. The paint of such .a type as to flow evenly when thus applied.

it is an object of the present invention to provide adevioearranged to accomplish the same purpose, but without the necessity of constantly dipping the roller into a shallow container of paint. As a result not only is the paint protected from the air, but also considerable time and work are saved.

A feature of the present invention lies in the provision of a roller for applying paint or the like, which is equipped with a pump device capable of lifting paint from a paint reservoir onto the surface of the roller. 'The pump device is connected with the roller in such a way that {the pumping means operates faster when the roller'travels at a greater speed. Therefore, the proper supply of paint is at all times delivered to the surface of the roller regardless of the rate of speed at which the roller is operating.

A further feature. of .the present invention lies in the provision of a roller having a paint supplying mechanism, such as a bristle brush, engaging the exterior surface of the roller so as to spread the paint uniformly on the surface thereof. The paint is fed through this bristle brush onto the surface of theroller.

A further feature of the present invention lies in the prowsion of a paint roller equipped with a reservoir of suificient size to contain a supply of ,paint sufiicient to cover .a-considerable area. Accordingly the reservoir .need .only be supplied with a fresh supply of paint .after an area of some size'has been painted.

"These and other objects and novel features of 'my invention will be more clearly and fully set "forth inthe followingspecification and claims.

In the drawings forming a part of my specification".

Figure 5 is 'a'sectional view through the lower end of the pumping apparatus showing the arrangement thereof.

Figure '6 is a sectional view of a modified form Qf construction of pumping apparatus.

The paint applying device or paint roller -A comprises in general a reservoir 4 0 provided with a flat rear wall M, a bottom wal-l I2 at --substantially right angles to the rear wall-and sloping-towa-rd one side wall, and side or end walls 13 and 14. An outwardly and upwardly inclined forward wall 1-5 terminates at a point substan tially below the level of the upper edge of the rear wall H, and a concaved wall 16 connects this sloping forward wall 1-5 to the top cover wall 11. V The top cover wall I 1, the rear wall ll, the bottom wall l2, the front walls 15 and Hi, and the side walls 13 and I4 are all connected together in any suitable way, such as 'by soldering, or the like, 'to form a closed container. A -filling sleeve 19 is mounted on the top wall I! and is normally closed by a cap or plug such as 20.

In order to properly manipulate the paint applying device I provide a handle '21 which may 'be secured in any suitable manner on the rear wall I l of the-reservoir. 'By'means of this handle the paint applying device may be readily moved along the surface of a wall.

An "arm '22, integral with the side wall 'l'-3,, extends forward-1y from the concave portion "l6 of the front 'wall to support one end of the paint applying roller. A pin '23 onth-e 'arm 22 engages into a socket 24 'inthe hub of 'a "beveled gear 25. This beveled gear 25 is supported in the end of'the roller 26 'which-is covered with a soft or resilient covering '21. The beveled gear 25 is shown connected directly to the roller '26, but obviously this "roller may be mounted on the pin 23 "in such a'manner 'as to be supported permanently thereupon "and may be key connected to the roller 26.

The other end of "the rollerZG is supported by The arm 29 is provided with a "pin '3! which is intended to engage in "an axial "socket -32 in the roller 26. A pivotal clip .33, -best illustrated in Figure '3 ofthe drawings, is pivoted to the 'reservoir at '34 and engages over the arm 29 to hold 3 the arm with its pin 3| engaged in the socket 32.

A transverse manifold 35 extends longitudinally of the roller 25 and above the same, this manifold being supported by suitable supports 36 projecting from the concave portion I6 of the reservoir. The manifold 35 is hollow and is provided with an elongated opening or series of openings 3'? spaced along its length. Bristles 39 depend downwardly from the manifold 35 to engage the' soft surface 2'! of the roller 25. Paint is permitted to flow through the opening or openings 31 and through the bristles 39, being spread by the bristles onto the surface 31 of the roller 25. A

The manifold 35 is connected by a tubular conduit 40 extending from one end of the manifold to a point adjacent the arm 22. A beveled gear 41 having an upwardly projecting hollow hub or sleeve portion 42 is journaled in the end of the tubular'conduit 40. The beveled gear 4| is designed to mesh with the beveled gear 25 and to be rotated thereby upon rotation of the roller 25.

The lower end of the bevel gear 4| is likewise provided with a hollow hub or sleeve 43 in the end of which is provided a spider 44 equipped with a bearing (l5, acting as a journal for the upper extremity of a Worm shaft 45. The worm shaft 46 operates in an upwardly inclined tubular conduit 51 and the lower end of the shaft 46 is j ournaled at 49 in the lower end of the conduit A15. The conduit 4'? is connected at its lower end by a passage 50 with the interior it of the reservoir Ill, and the flow of paint or other fluid through the passage 50 is regulated by means of a needle valve 5!. By operation of the needle valve 5| the amount of paint flowing through the passage 50 may be regulated.

A worm conveyor 52 is provided on the shaft 46 to rotate therewith. This conveyor may be of the spiral type and operates to elevate the fluid through the hollow hubs of the bevel gear 4! and through the conduit 40 to the manifold 35 from which the paint is allowed to spread onto the roller 26. Rotation of the roller 26 acts through the bevel gears 25 and 4| to rotate the worm conveyor 52 and to thus elevate the paint.

If it is so desired a pressure pump may be used in place of the worm conveyor '52 to elevate the paint. In Figure 6 of the drawings I have discloseda reservoir I5 having an end wall l3 adjacent which is secured a tubular conduit 41. A pump chamber is provided at the lowermost extremity of the conduit 41. This pump chamber is connected by the passage 53 to the in.. terior of the reservoir ID. A needle valve 54 is provided in the passage 53 to regulate the flow of paint into the pump chamber.

The shaft 45' driven by a bevel gear similar to the gear 4! extends into the pump chamber, and an eccentric pump 55 is mounted thereupon to rotate in the pump chamber and force fluid from the inlet passage 53 out through the outlet passage 55. Therefore, upon rotation of the roller, fluid is pumped through the conduit 41', the hollow center of the bevel gear ll and the conduit 40 to the manifold 35. a

The sizes of the conduits conveying paint to the manifold may be regulated, depending upon the desired flow. While the conduits are shown of considerable diameter, in the particular form illustrated, so as to accommodate the worm 52, the size of these conduits may be materially reduced, particularly if the pressure pump is used for forcing the paint to the manifold 35.

In accordance with the patent statutes, I have described the principles of construction and operation of my paint applying roller, and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
